I have the same problem, a 32 bits toshiba nb255, it first had the windows 7 bu next I installed the ubuntu 11.04. The wifi does not turn on. I used the following issues
the commands rfkill unblock wlan0, sudo ifconfig wlan0 down; they were not able.
by setting up the bios in advanced menu, the wireless communication sw in ON, but it did not work also.
neither the utilities toshiba nor utilities of ubuntu (wicd, wifi radar).
by using gedit to file group, nothing.
by installing madwifi packet, nothing.
by exporting the wifi driver from windows to ubuntu, by means of the NDISwrapper packet, neither.
I put the current scripts of the ouput of the cli

note.-it is logical all the counters are cero if the wireless device is down
root@zorrillo:/home/zorrillo/Descargas/802BGA# ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill
root@zorrillo:/home/zorrillo/Descargas/802BGA#
It would seem the wireless switching does not react with whichever ubuntu 11.04 command (I hope to be wrong). The target remains the same, in order of the scripts above.
I am worried, I have tried to find any answer for days and nights. Toshiba does not supply drivers or soft support for linux, marketing of course.
I only see the device is up by protocols and down phisically, My question is, is it possible to enable or not shutdown physically the device?,
because in the toshiba model nb255 the wifi is not set up/down bye means of a physical switch, but by means a combination of Fn + F8 (only for windows 7, no one more), Is there one possibility to configure the hot keys in ubuntu?
